Longblock includes with dry joint manifolds and elbow set
This Mercruiser remanufactured Longblock suits Mercruiser 4.3L and 4.3L MPI engines up to 2006 models with CPS
This is the best alternative to repair your seized 4.3L / MPI engine as you can no longer buy 4.3L or 4.3L MPI new replacement engines
Mercury Remanufacturing refurbishes MerCruiser engines and components to current specifications. This provides the most powerful and reliable engines at a fraction of the cost of new. We stand behind all of our remanufactured products with the same one-year limited factory-backed warranty as we do with all of our new parts and accessories. Mercury Product Protection is even available for our remanufactured engines for up to three years of coverage.
Much tougher. And much better. They have to be after what we put them through. It starts here at the Mercury factory. It’s the only place we remanufacture engines. Back where they were first designed and built. First thing we do is full dis-assembly. The powerhead is completely taken apart and goes through a four-step, high-pressure “hot” cleaning process. We inspect everything. We machine, bore, and hone critical components to original tolerances. We replace cracked or corroded components (no weld repairs like you’ll find with the aftermarket guys). We replace the oil pump, the valve springs, and all fasteners. We apply new paint. And finish up with a process nobody in the aftermarket can or will do. Hot testing. We fire up the engine and run it for at least 15 minutes under pressure. See if the oil and coolant are doing their job. See if the engine performs to the same high standards as a new MerCruiser engine. And to make it official, we back it the same way. With the same MerCruiser one-year limited factory warranty.
The aftermarket fix. What it saves you could really cost you.
Yes, there are aftermarket operators out there. Might be a machine shop down the street or across town. What they have is a low price. What they don’t have is everything else. They don’t have Mercury engineers. They don’t have the depth of knowledge. They don’t have the rigorous testing. They’ll often fix a bad part, grinding it or welding it, rather than replacing it. And when they do replace, it won’t be with genuine MerCruiser OEM parts. They may not even be marine grade. Might be “will fits” or off-the-shelf automotive parts that aren’t made for the tougher conditions, heavier loads, and higher rpms a marine engine has to endure. Fact is, too many engines go to an aftermarket operator as a marine engine and come back as a car engine. And that can cost you big time in the long run.
